SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 308,892, dated December9, 1884.

l Application filed February 28, 1884. (No model.y

To aZZ whom it may concern:

Be it known that I, GASPAR J. HAAs, a citizen of the UnitedStates,residing at Flint, in the county of Genessee and State of Michigan, haveinvented a new and useful Self-Heating Sad-Iron, of which the followingis a specification.

My invention relates to improvements in sad-irons of that class whereinthe body or main part of the iron is made hollow and provided with ahinged cover to receive charcoal or other fuel, the combustion of whichkeeps the face of the iron raised to 'the proper temperatu're.

The invention is fully illustrated in the accompanying drawings, inwhich Figure l is a longitudinal vertical section at x m in Fig. 2. Fig.2 is a transverse vertical section at y y of Fig. 1. Fig. 3 is aperspective view showing* the front end of the iron and the blow- `outvalve opened, also with the chimney removed to show the front standardand a part of the handle-bolt. Fig. 4L is a sectional View of the same,but with a different locking device.

Similar letters of referenceindicate like parts in the several figures.

A represents the hollow body, having an elevated stem, a, at the nose,to which hingelu gs Z1 b of the top or cover B are pivoted, as shown.

B is the front standard, which rises from and forms an elevated segmentof the pipecollar c, over both of which the pipe-elbow C slips. y

B2 is a rear standard, having a stud on its base passing through a holein the heel end of cover, to which it is secured by riveting said stud.

D is a wooden handle between the standards B B2, secured in place byabolt, d, passing through them and said handle, with a nut at the frontscrewed on from the inside of the pipe-elbow, which is also thereby heldiirmly in place. rlhe cover is locked to the body by a lever-latch, E,pivoted at e between lugs on the rear face of the standard B2.V Aspring,

. f, throws its bent lowerend, g, into a hole, h,

drilled in the` back end of the bpdy. A slight pressure on the upper endof the latch E will withdraw its end g from the hole h and allow thecover to be thrown up and forward.

A is the draft-hole in the heel of the iron,

and A2 is the blow-out hole inthe nose thereof.

G is an inclined and curved grate laid in the bottoni of the iron tosupport the incandescent fuel, while the ashes may drop to the bottomand be blown out through the hole A2, using a handbellows for thispurpose, whose nozzle is inserted in the hole A.

H is a disk-register, pivotcd at i to the heel.` By rotating thisregister the draft may be regulated or sluit off at will.

I is a valve to close the blow-out. The nose of the iron is milled orbored into, leaving a iat spot across its front end, to which the valveI is pivoted by a center bolt, j. The valve is nearly triangular incross-section and conforms to the outline of the iron at the nose whenclosed. A spring-bolt, J, in the upper end of the valve locks it in theclosed position by its point entering a concavity inthe milled face. Itwill be noticed that the upper half' of the rear face of said valve ischamfered off,

as at z', also that its pivot-hole is not drilled to fit the pivot j,except at the inner end, but is reamed on a taper, as seen at i. Thispermits the valve to rock a little on its pivot, so that it will beloose and turn freely on its axis as soon as the lspring-bolt is movedou`t of its socket, and thus allow the valve to be easily manipulated,the spring-bolt serving asa handle with which to swing it.

It is found in practice that under repeated reheatings ofthemetaloxidation and other chemical changes induced thereby will causescrews and nuts to stick fast, and therefore box-irons having valves orregisters hung on screw-clamping pivots soon become useless by theirvalves and registers so fitted. This objection cannot be raised againstmy described construction, which allows the valve to be firmly seatedwhen closing the blow-out, but to swing loosely when turned to open it.

I do not wish to confine myself to the particular spring-bolt shown inFig. l for locking said valve I, for without departing from the spiritof my invention other devices may be used for the purpose, one of whichI show in vertical section in Fig. 4, wherein K is a lever, pivoted at LtoV lugs on the valve I above its axis, terminating at its upper end ina crank, K. The foot of said lever enters a socket or depression, m, inthe nose of the iron when the valve closes the blow-out. The lower end`ICO of said lever is bent inwardly with a spring, 2. The valve I,ehamfered as at z', and havn, spirally coiled about it, and, interposedbelng rea-med or tapering pvot-hole i', combined tween said lever andthe lower part of the with the iron A, pivot j, and securing-bolt,

valve, keeps the latter closely seated. as and for the purposes setforth. 5 I claimp l. In a sad-iron, substantially as described, I GASPARJ. HAAS.
